SHIP S Specification of Letters Patent N 0. 26,650, dated January8,1860.

To all whom it may concern:

Be it known that I, J. THEODORE OHABoT, of the city of Buffalo, in thecounty of Erie, in the State of New York, have invented new and usefulImprovements in Steering Apparatus; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference markedtherein, making a part of this specification, in which- Figure l is atop side view of the deck V of vessel, illustrating the arrangement ofthe steering wheel M, connected to a straight tiller E and double blocksy, 3 Fig. 3 the upper and lower shells of block 1 y with strap a. Fig. 2the upper and lower straps c, a. One way '0, roller w and one blockshell 6 and rollers; same letters referring to like partsin all of thedrawings.

The nature of my improvements consists in arranging the double blocks y3 with the sliding block 2?, t, upon the forward end of straight tillerE, moving upon the square surface P, of tillers, as an advantage gainedin controlling vessels.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

Fig. l the chain makes five turns around the drum L part of which 71,extending downward underneath the friction pulley Z2, passing to theleft and around the stationary pulley c, at right angle; also to andaround the rear stationary pulley e 8 around the left block y, andunited to a stationary point, W, near the sheave 0r pulley e s. Theother part of chain K extending downward and underneath its pulley b andto and around the right stationary pulley t a of the stationary block aat a ri ht angle, passing tothe rear parallel with t edeck V, to andaround the right stationary pulley e s and toand around the right block3 and to the right stationary point W. A portion of the chain TILLER.

and lower shell with friction rollers located 1 between, and at each endof the shellst, t,as 5 5 seen in Fig. 2. The block 25,15, isgalso united1 by an upper and lowerstrap c, c, as also seen in Fig. 2, with theattachment ofthe left j block, 1, and encompassingthe lower shells t lin Fig. 2, and the tillerfcenter beam E, as. also seen in Fi l The uppershell t and strap 0, are united by a center bolt, as well asthelowershell t and strap 0, separately. I;The screw swivels r, r, may beconnectedto thechain ill/and K, at the stationary points W, WgThe uppercenter bolt has a. frictionroHerCX 1 3 inserted; moving upon: thesurface of the. 1 Ways or wayo, which may be united to deck l of vessel,as seen inFig. 2. a l

Operation: The straighttiller is moved right and left by its connectionto steering wheel M with chain it rod J, and the other e part K androdJ, as seen in Fig, 1, arranged underneath the deck V of vessel inpart; p a portion of the deck beingleftlofhin order Y 1 to present thesame. The double blocks 1} with sliding blockt t, moves right and leftupon the surface P of tiller; thereby the tiller E is permitted also toswing left anu right, as indicated by the dotted lines The poweroftiller E; or lever is increase i in proportion to thedraft of waterupon the rudder blade, as the tilleriis moved either: 1 1 right or leftfrom midship. The rear portions of chain it and K move upon a straight.line, while the movements of tiller E .describe acircle, from the rudderpost as its, 1, center. The straight tiller E may be used without theslidingblocks or with the; e 1 sliding blocks j 1 Vhat I claim asmyinvention and desire, l to secure by Letters Patent is; a f p l Thesurface P of the, forward end I of straight tiller E in formrepresenting a allelogram, in combination with the slirii block 2? t andits friction rollers; double h, is may be supplied at the center withthe rods J J. The surface of straight tiller bar E, from the point ofits connection to the side bars F, F, extending forward to the stay boxa, is flattened, forming a parallelogram and for the horizontal movementof the sliding block if t of tiller E. The

block 3 y, lower and upper strap 0,0, with center bolts located at thecenterof til E; as described in the foregoingspecifica tion.
